python-pro
Use when building Python 3.11+ applications requiring type safety, async programming, or robust error handling. Generates type-annotated Python code, configures mypy in strict mode, writes pytest test suites with fixtures and mocking, and validates code with black and ruff. Invoke for type hints, async/await patterns, dataclasses, dependency injection, logging configuration, and structured error handling.

Discovery
100%Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.
This is a strong skill description that excels across all dimensions. It provides specific concrete actions, includes natural trigger terms that developers would use, explicitly states both what the skill does and when to invoke it, and carves out a distinct niche around modern typed Python development with specific tooling.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Lists multiple specific concrete actions: 'Generates type-annotated Python code', 'configures mypy in strict mode', 'writes pytest test suites with fixtures and mocking', 'validates code with black and ruff'. These are detailed, actionable capabilities. | 3 / 3 |
Completeness | Clearly answers both what ('Generates type-annotated Python code, configures mypy...') AND when ('Use when building Python 3.11+ applications requiring type safety, async programming...' and 'Invoke for type hints, async/await patterns...'). Has explicit trigger guidance at both the beginning and end. | 3 / 3 |
Trigger Term Quality | Excellent coverage of natural terms users would say: 'Python 3.11+', 'type hints', 'async/await', 'dataclasses', 'pytest', 'mypy', 'black', 'ruff', 'dependency injection', 'error handling'. These are terms developers naturally use when requesting these capabilities. | 3 / 3 |
Distinctiveness Conflict Risk | Clear niche focused on modern Python with specific tooling (mypy strict mode, pytest, black, ruff) and patterns (type safety, async, dataclasses). The combination of Python version, strict typing, and specific tools creates a distinct profile unlikely to conflict with generic Python or other language skills. | 3 / 3 |
Total | 12 / 12 Passed |
Implementation
100%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This is an excellent skill file that demonstrates best practices across all dimensions. It's concise yet comprehensive, provides executable code examples for every pattern, includes clear validation workflows with feedback loops, and uses progressive disclosure effectively through the reference table. The MUST DO/MUST NOT DO constraints are specific and actionable.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The skill is lean and efficient, avoiding explanations of basic Python concepts Claude already knows. Every section serves a purpose with no padding or unnecessary context about what Python or type hints are. | 3 / 3 |
Actionability | Provides fully executable, copy-paste ready code examples for all major patterns (type-annotated functions, dataclasses, async, pytest). The mypy configuration and expected output are concrete and specific. | 3 / 3 |
Workflow Clarity | The Core Workflow section provides clear sequencing with explicit validation checkpoints and feedback loops (if mypy fails → fix → re-run; if tests fail → debug → iterate). This addresses error recovery for the validation step. | 3 / 3 |
Progressive Disclosure | Well-structured with a clear reference table pointing to one-level-deep topic files. The main skill provides a complete overview while signaling where to find detailed guidance for specific topics. | 3 / 3 |
Total | 12 / 12 Passed |
